GADDIS, OF CLEVELAND, OHIO, ASSIGNOR TO GLOBE MACHINE & STAMPING' COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO INSERT FOR CONCRETE Application led January 23, 1928.v Serial No. 248,602.

This invention relates to inserts for concrete and particularly to devices of that nature intended for supporting a pipe hanger or other suspension device, from the ceiling of a room. v

It is one of the objects of the invention Yto provide an insert that mayV bel made from sheet metal at a minimum cost and which will be securely held in concrete and alsol adapted for convenient application and vso formed that the concrete will readily. flow Y Fig. 2 is a transverse section'through theV insert illustrated in Fig.,1 and showing the arrangement of the concrete thereon as well as the position of a pipe hanger therein; and Fig. 3 is a central longitudinal section of the insert shown in Fig. l.

Referring to the drawings, 10 indicates the main body portion of the insert which is provided with upright side walls 11 and 12 and a bottom wall 13. The body portion 10 is made from sheet metal and the upper portions of the side walls are bent inwardly as shown at 14 and then outwardly as shown lat l5 to form means for securely bonding the insert to the concrete. The bottom wall 13 is provided with a slot 1G through which a nut- 17 or other supporting device may be in serted and, ordinarily, a hanger bolt 18 will be secured to the nut 17, or its equivalent.

An inverted` U-shaped vmember .19 is arranged within the body portion 10 with its longitudinal edges in engagement with the inner surfaces of the sidewalls thereof, soas to form a pocket 20 for the nut 17, from which the concrete will be excluded. The lower edges of the end walls of the member 19 have outwardly projecting flanges 20 which are preferably spot-welded to the upper surface of the bottom Wall v13 to thereby secure the parts together. The bottom wall 13 is preferably providedwith perforations 21, adj acent its ends, through which nails or wires may pass for the purpose of securing the insert to the concrete forms, prior to the pouring' of the concrete. The upper portions of the side walls 11 and 12 are preferably provided with elongated openings or vslots 22 through which the concrete may pass,.for the purpose of bonding the concrete, on opposite sides of the side walls and also to provide means for'better securing the insert to the concrete. l

vThe insert 19 vmay be made of a strip of sheet metal, of lighter gauge than the .body

portion 10, as the only purpose of the member 19 is to provide an open space within the insert and also to brace the side walls against Y j the pressure of the concrete on the outer sides thereof.

While I have illustrated and described what I now consider to be the preferred forni of my invention, it will be understood that some changes may be made in the details of construction without depart-ing from the Y spirit of the invention as it is defined in the appended claim.

Having thus described my invention what l claim is:

An insert for concrete consisting of a sheet metal body having bottoni and side walls andl open ends, said ybottom wall having an opening therein through which a nut may be inserted, and an inverted U-shaped sheet-metal member arranged between said side walls with its longitudinal edges in engagement therewith and with its vertical sides spaced inwardly from the ends of the walls ofrsaid body, said vertical sides having outwardly bent flanges secured to the inner face of said bottom wall and 'lying wholly within the spaces between saidi vertical sides and the ends of the walls of said body. s

In testimony whereof, I' hereunto afiiX my signature. v
